How do I convert Markdown to PDF?

Simply paste your Markdown text into the Markdown Flow editor on the left side, and click the 'Export PDF' button on the preview panel. The tool will automatically render your Markdown, including LaTeX and Mermaid diagrams, into a high-quality PDF document.

Can I convert Markdown to Word (DOCX)?

Yes, Markdown Flow supports exporting Markdown directly to Microsoft Word (DOCX) format. Paste your text, such as output from ChatGPT, Claude, or Gemini, into the editor and click the 'Export DOCX' button to download a formatted Word document.

How do I paste AI-generated Markdown (ChatGPT, Claude, Gemini) into Word?

Copy the Markdown output from any AI tool such as ChatGPT, Claude, or Gemini, paste it into the Markdown Flow editor, and click 'Export DOCX'. All formatting, bold text, lists, and code blocks will be perfectly preserved in the resulting Word document.

How to Write Chemistry Formulas in Markdown

July 11, 2026

2 min read

Standard Markdown has no way to represent a chemical formula - subscripts, superscript charges, and reaction arrows all need special notation. Markdown Flow supports mhchem chemistry syntax on top of its LaTeX math rendering, so formulas and full reactions render correctly.

Writing a Simple Formula

Wrap a formula in math delimiters using the \ce{} command:

Water: $\ce{H2O}$

Sulfuric acid: $\ce{H2SO4}$

Numbers after an element automatically render as subscripts - no manual formatting needed.

Writing Full Reactions

Reactions with arrows, conditions, and multiple compounds work the same way, typically as display equations:

\ce{CO2 + C -> 2 CO}

Ions, Charges, and Reaction Conditions

mhchem also handles charges and conditions written above reaction arrows:

\ce{Hg^2+ ->[I-] HgI2 ->[I-] [HgI4]^2-}

That single line renders a full mercury-iodide reaction sequence, complete with charges and the reagent labeled above each arrow.

Where This Comes Up

Chemistry homework and lab reports written with the help of an AI assistant.
Study guides that mix explanatory text with formulas and reaction equations.
Technical documentation in materials science, pharmacology, or environmental science.

Exporting Chemistry Notation

Chemistry equations follow the same export rules as regular math: PDF export renders them exactly as shown in the preview, and DOCX export keeps them as readable text so they display correctly in Word.

Frequently Asked Questions

Do I need special syntax knowledge beyond \ce{}? For most simple formulas, no - just wrap the formula in \ce{} inside math delimiters. Reactions with arrows and conditions use the same command with a few extra symbols (->, ^, [ ] for reagents).

Does this work alongside regular math equations? Yes - you can mix \ce{} chemistry notation and standard LaTeX math freely in the same document.

Can I ask ChatGPT to generate the formula for me? Yes - ask for a chemical equation and most AI assistants will already respond with \ce{} syntax, since it's a recognized LaTeX chemistry convention.
